4．Operation

4.1 Operation Modes

The UPS is a double-conversion on-line UPS that may operate in the following alternative

modes：

◆Normal mode

The rectifier/charger derives power from the AC Mains and supplies DC power to the inverter while floating and boosting charge the battery simultaneously. Then, the inverter converts the DC power to AC and supplies to the load.

◆Battery mode (Stored Energy Mode)

If the AC mains input power fails, the inverter, which obtains power from the battery, supplies the critical AC load. There is no power interruption to the critical load. The UPS will automatically return to Normal Mode when AC recovers.

◆Bypass mode

If the inverter is out of order, or if overload occurs, the static transfer switch will be activated to transfer the load from the inverter supply to bypass supply without interruption to the critical load. In the event that the inverter output is not synchronized with the bypass AC source, the static switch will perform a transfer of the load from the inverter to the bypass with power interruption to the critical AC load. This is to avoid paralleling of unsynchronized AC sources. This interruption is programmable but typically set to be less than an electrical cycle e.g. less than 15ms (50Hz) or less than 13.33ms (60Hz).

◆Maintenance mode (Manual Bypass)

A manual bypass switch is available to ensure continuity of supply to the critical load when the UPS is out of order or in repair. This manual bypass switch is fitted for all UPS modules and bears for equivalent rated load.

◆Redundancy mode

Based on different demands, The UPS can be set as N+X redundancy mode to increase the reliability to the load connected.

4.2 Turn on/off UPS

4.2.1 Restart procedure CAUTION! MAKE SURE GROUNDING IS PROPERLY DONE!

16

◆ Set the Battery Breaker to the “ON” position according to the user’s manual.

◆ Open the front and rear doors of the UPS to access to the main power switches.

During this procedure the output terminals will become alive.

CAUTION！

Check to see if the load is safely connected with the output of the UPS. If the load is not ready to receive power from the UPS, make sure that it is safely isolated from the UPS output terminals

◆ Check the status of the power switch of the monitoring module. Defualt is set at “ON”.

Turn ON the power switch of the monitoring module, so that the UPS system can communicate normally through the monitoring unit. When hot-swap this monitoring unit, the power switch must be OFF.

◆ Turn ON the input switches of all UPS modules, which locate at the modules’ rear panels.

When AC MAINS input voltage within the range, the MAINS LED of the UPS modules will light up accordingly. And the rectifiers of the UPS will be started up in 30 seconds, then the inverter is started completely. When the output breaker is “ON”, the inverter LED lights up.

◆ Switch ON all output breakers, which locate at module’s front panel.

If the rectifier of the module does not start-up, the bypass LED and Output LED will light up. When the inverter is on, the UPS will transfer from bypass mode to inverter mode, then the bypass LED is off and the inveter LED is on.

No matter the UPS is operated normally or not, the LCD display will indicate current status. The top lines display the UPS operational status and the bottom lines indicate alarm conditions when they occur.

17

4.2.2 Test procedure

CAUTION! The UPS is operating normally.

It may take 60 seconds to boost up the system and perform self-test completely.

◆ Switch off the MAINS to simulate utility failure, the rectifier will turn off and the battery should feed the inverter without interruption. At this time, the LEDs of battery, inverter and output should be turned on.

◆ Switch on the MAINS to simulate utility recovery, the rectifier will restart automatically after 20 seconds and the inverter will supply to the load. It is suggested to use Dummy

loads for testing. The UPS can be loaded up to its maximum capacity during load test。

4.2.3 Black(Cold) start procedure
